abstract class to write a scene to a file
Definition: vtkExporter.h:47
represents an object (geometry & properties) in a rendered scene
Definition: vtkActor.h:45
virtual void WriteData()=0
int vtkIdType
Definition: vtkType.h:347
export a scene into a single vtp file and png texture
concrete dataset represents vertices, lines, polygons, and triangle strips
Definition: vtkPolyData.h:79
a simple class to control print indentation
Definition: vtkIndent.h:33
handles properties associated with a texture map
Definition: vtkTexture.h:65
void PrintSelf(ostream &os, vtkIndent indent) override
Methods invoked by print to print information about the object including superclasses.
static vtkObject * New()
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
